I think the above is about right. (as an example, a version 2 library needs a new claim).
And someone taking over maintenance of a library needs to add a new claimant.

Also don't ever remove previous copyright claims - just add new claims and/or claimants. A reason for doing this is that it would
remove the earliest claim date, something that may establish a 'prior art' date that might prevent anyone patenting.
